The mixer emphasizes precise control over audio signals, with features like phantom power, equalizers, and level meters, ensuring high-quality sound output and flexibility for complex setups.

Key Features

1. Phantom Power (+48V) Switch
   • Toggles +48V phantom power on/off for condenser microphones, enabling compatibility with professional-grade microphones requiring external power.
   • Located on each input channel for individual control.
2. Low Cut Filter (80 Hz)
   • Activates a high-pass filter that cuts frequencies below 80 Hz, reducing low-frequency noise such as stage rumble or electrical hum for clearer audio output.
3. Trim Control for Input Sensitivity
   • Adjusts input signal levels for both microphone inputs (-60 to +10 dB) and line inputs (-40 to +10 dB).
   • Optimizes signal-to-noise ratio and dynamic range, with a PEAK indicator that lights briefly during high transients to prevent clipping.
4. PAD Switch (-20 dB)
   • Reduces the signal sensitivity of each channel by 20 dB, allowing the mixer to handle high-output sources (e.g., loud instruments or line-level devices) without distortion.
5. Three-Band Equalizer (High, Mid, Low)
   • Provides independent control over high, mid, and low-frequency bands per channel.
   • Setting the knob to “0” ensures a flat frequency response, while turning left attenuates the respective band for precise sound shaping.
6. Auxiliary Sends (AUX1–AUX6)
   • Features six AUX send channels for routing signals to external devices (e.g., monitors or effects processors).
   • AUX1–AUX4 include a PRE switch to select pre-fader (unaffected by channel fader) or post-fader signals, ideal for monitor mixes or effects sends.
   • AUX5 and AUX6 have dedicated level controls for fine-tuned auxiliary output adjustments.
7. Built-in Effects Processor (FX1 & FX2)
   • Includes two effects processors (FX1 and FX2) with adjustable parameters via dedicated knobs.
   • FX sends allow direct routing of channel signals to the built-in effects, supporting effects like reverb or delay.
   • FX to AUX control enables adding effects to auxiliary outputs for enhanced monitor mixes.
8. Pan Control
   • Adjusts the stereo positioning of each channel’s signal within the stereo image.
   • Supports subgroup assignments (e.g., routing to G1-G2 or G3-G4) for flexible signal management in live or recording scenarios.
9. Mute and Solo/Peak Switches
   • Mute Switch: Silences individual channels instantly, useful for isolating or muting specific inputs during a performance.
   • Solo Switch: Enables isolated monitoring of a channel via headphones, ideal for previewing channels in live settings or troubleshooting during sessions. Multiple channels can be soloed simultaneously.
   • Peak Indicator: Flashes when the input signal is too high, alerting users to adjust levels to avoid distortion.
10. Main and Group Outputs
    • Main Out (L/R) Jacks: Delivers the mixer’s stereo output for connection to power amplifiers or main speakers.
    • Group Outputs (G1-G2, G3-G4): Provides additional routing options for subgroup mixing, controlled via dedicated faders after pressing corresponding switches.
11. Channel and AUX Level Faders
    • Individual channel faders adjust the output level of each channel, allowing precise control over the mix.
    • AUX level faders control the output of auxiliary channels without affecting the main mix, ideal for monitor or effects sends.
12. USB and Soundcard Integration
    • USB Interface: Allows connection of a USB device for playback or recording.
    • Soundcard Input Port: Supports connectivity with PCs or phones for digital audio interfacing, enabling recording or playback via software.
    • MP3 Control Zone: Includes Play/Pause, Next/Previous, and Volume +/- buttons for managing MP3 playback, plus a REC button for initiating recordings and a MODE button for switching to recording or Bluetooth mode (if available).
13. Headphone Output and Control
    • TRS headphone jack for monitoring, with a dedicated Phone Level Control knob to adjust headphone output volume independently of the main mix.
14. Level Meters and Input LED Display
    • Level Meters: Display the signal strength of AUX outputs, providing visual feedback for monitoring levels.
    • Input LED Display: Shows input signal strength for each mono channel, helping users monitor and adjust levels to prevent clipping.
15. Toggle Keys for Input and Group Selection
    • Input Toggle Keys: Switch between input sources, such as channels 11/12, MP3, or soundcard inputs, for flexible signal routing.
    • Group Toggle Keys: Allow monitoring of group signals (1-2 or 3-4) for subgroup management during mixing.
16. Stereo Input and Output Jacks
    • Stereo Input Jacks: Connect to external devices like cassette decks for additional input sources.
    • Stereo Out Jacks: Designed for recording the mixed output to devices like cassette decks.
17. Power Switch and Safety Features
    • Power Switch: Turns the mixer on/off, with a recommendation to switch off before connecting to mains power.
    • Safety Instructions: Includes warnings to avoid moisture exposure, ensure proper ventilation, and use a polarized or grounding-type plug for safety. The mixer should be connected to a protected MAINS socket, and the power cord should be positioned to avoid damage.
18. Multifunctional Zone
    • Provides additional controls for adjusting effects parameters and selecting effect types, enhancing the mixer’s versatility for live and studio applications.
19. Recording and Playback Controls
    • Dedicated REC volume control and recording interface for capturing audio directly from the mixer.
    • MP3 controls allow seamless integration of digital audio playback and recording.
20. Robust Design and Accessibility
    • Designed for professional use with no user-serviceable parts inside, requiring qualified personnel for servicing.
    • Easy-to-access power plug and MAINS disconnect for safe operation.
